Requirements

Debian-flavor "ifstat command". Run "ifstat -v"; You should have version 1.1.

realpath command for setup.sh. Run "realpath --version" to see if you have it installed. Use apt-get or pacman to install it depending on which linux distro you are using.

Arch Linux users: You WILL have to download the source code for ifstat and compile it yourself if you want to monitor a network interface with this script. Arch Linux's ifstat command output format is significantly different from Debian's ifstat. You will otherwise have to modify rpi2pachube to work with whatever flavor of ifstat Arch Linux uses if you do not wish to do this.

Create a feed on Pachube

Create an account on Pachube if you don't have one already and log in with your account.

Add a new device/feed by clicking on the +Device/Feed button.

Select "Something else" when prompted for device type.

Select "No, I will push data to Cosm" when asked for an existing data source.

Update (Wed, Jan 23rd, 2013): Added "realpath" as a requirement. Renamed script to rpi2pachube and moved repository to a new location.
